1984 was a classic satire as well as a warning. Ironically, when Orwell wrote it, the Org wasn't (IMHO) actually anywhere near as Orwellian as it is today.
Telling quote: I mentioned recently to my mom (a devout Witness) how the whole thing seemed awfully "Big Brother" to me, and she actually replied, "Well, honey, don't you think Jehovah is Big Brother"?
Talk about an unintentionally spot-on and chilling reply.
